artificial turf
First, artificial turf to introduce performance
(A) the advantages of artificial turf
Evergreen: The artificial turf is a special paint-stained from long exposure to the sun, or in the wet in the rain, still colorful forever.
Authenticity: a soft silk grass, and very similar to natural grass, standing above the grass like a real person in general. Also because of their extremely low reflection coefficient, so it will not cause eye fatigue.
Durability: No matter the wind, sun, rain, do not become brittle contraction; high-density, flexibility, after the return to the weight of good, flexible wear.
Practical: do not drop attachment, the hydrophobic fast, keep dry grass to avoid the mud, high utilization rate.
Buffer: with the impact of their own ability to campaign in the fall and collision, will not lead to injured athletes.
Fire: fire retardant to ensure safety in public places.
Anti-power: to prevent static electricity.
Of pollution: special treatment will be applied to textile materials isolated blemish on the use of foreign elements on artificial turf. Can be maintained for a long time clean, very stain resistant, the material characteristics.
Heat: direct sunlight, gentle to the building of heat reflective, heat-resistant thermal effect, heat-absorbing about 4 .
Noise: the sound of good noise absorption of about 20 dB.
(B) the scope of application of artificial turf
Soccer field, tennis courts, basketball courts, golf courses, field hockey, track and field, construction, the top layer, a swimming pool, gardens, nurseries, hotels and so on many occasions.
Second, artificial turf on the basis of the requirements of
(A) artificial turf on the quality of the cement concrete layer:
General Technology
1, natural-soil: density greater than 95% moisture content 8-12%. Fu Zhitu and eradicate turf after 12 tons of rolled along the vertical plane from the middle to both sides of the RCC to 5-8 times.
2, natural gravel layer: thickness of about 100mm, the largest particle size of not more than the thickness of the bottom of the 2 / 3, to 60% of the aggregate content is appropriate, with about 12 tons of rolling machine rolled over 5-8.
3, gravel layer: a thickness of about 30mm (size 20-30mm), 12 tons of rolling machine rolling stone not to loose, no ripple on the surface, compaction density of 2.2 tons / cubic meter.
4, cement concrete layer:
(1) should be used more than 200 laying cement concrete as a whole, the surface of mortar 1:1.
(2) flat-panel vibration, cement slurry when it closed wooden box with rough-cast.
(3) solidification of cement, between 4-5m cut expansion joints (width 8-10mm, deep 30-40mm)
(4) in the thickness of the concrete around 80mm.
quality requirements:
1, after the completion of the foundation, cement surface may not be too smooth, since no sand, cracks and peeling from crusts and so on.
2, flatness: 3m ruler to allow less than 3mm of error.
3, slope: Sports technology in line with the targets.
4, compressive strength: R20> 25kg / cm2
R50> 10kg / cm2
5, surface-based non-blocking phenomenon.
6, the maintenance period: outdoor temperature of 25 for more than 24 days.
Outdoor temperature 15 -25 between 30 days.
15 air temperatures below 60 days.
(In order to cement the volatile components of Alkaline, maintenance and more water during)
7, the laying of the plastic layer, layer should be the basis of oil-free, ash-free, dry.
(B) of the artificial turf Maintenance Information
1, the ban on wearing long 9mm or 9mm over the running spikes on the lawn.
2, to prohibit any motor vehicle traveling on the lawn.
3, long-term ban on heavy pressure on the lawn.
4, prohibit the shot put, javelin, discus, or other high-fall campaign carried out on the lawn.
5, the event immediately to prohibit snow stampede, to be floating on the surface will be carried out after the snow Saojing use.
6, in time to clear the lawn of the foreign body, leaves, pine needles, nuts, gum, etc. can cause tangles, litter spots and stains.
